The problem was (the same condition of the bOnlyFrameStarts parameter
was used during output of Start and End bookmarks):
  if (BkmType::Start == pPtr->nBkmType && !bOnlyFrameStarts)
  ...
  if (BkmType::End   == pPtr->nBkmType && !bOnlyFrameStarts)
  ...
Should be:
  if (BkmType::Start == pPtr->nBkmType &&  bOnlyFrameStarts)
  ...
  if (BkmType::End   == pPtr->nBkmType && !bOnlyFrameStarts)
  ...

I assume this was a simple copy-paste bug.
